    Question Transitioning between land and snow?

    Hi, this is my first post on the site, but I've been using the tutorial forum for a while now. Have to thank RobA for his amazing tutorial on artistic maps, it helps create such a better atmosphere to have an artsy map for my DnD players.

    I have a question, which is why i'm posting here.

    I'm currently mapping an entire continent in sections because not all of it is necessary and it's easier to do in sections. However a problem with this is that the northern part of the continent is snow and ice, while the southern part is not. In one particular section, there has to be a transition.

    How can I seamlessly transition between land and snow? I had some thoughts about possibly using a gradient and a noise/bump map like in RobA's tutorial. But I need the texture to increase as you go northwards on the map because of snows melting rate the further south. I can only get the texture to remain consistent.

    Anyone have any ideas?

    Thanks in advance.
    JC

    Theoretically, meaning I've never tried it as my style's a bit different... You may be able to use a bump/noise layer with a layer mask to soften/erase the texture where you don't want it. Just a guess, might not work.

    Thankyou so much for your suggestion Chashio, it worked perfectly, with a little fiddling around.

    Step by step;

    1. I did the dirt layer as normal.
    2. Created a snow mask channel.
    3. Created the texture and bump mapped.
    4. Add the layer mask and then blur the mask.
    5. Repeat step 4 2-3 more times depending on how smooth you want the transition.
    6. Apply a final layer mask of the snow channel to cut the edges off.

    Texturing isn't perfect and the map is a little basic for now (it's nowhere near finished, just wanted to show the final product of the snow).

    That looks really good

    Even if I am correct, I would still advise you to follow your heart. This whole Cartographers Guild thing, it seems to me, is more about passion and skill and learning new techniques than it is about definitions and rules.

    Late to the game here. I like to use the spread filter gimp has to get a snow edge. This makes the white "taper off" in a clumping manner, rather than fade.

    Similarly, you could set your snow layer to the "dissolve " blend mode if you already have a transparency fade...
